Methods

map<R>({required R data(AsyncData<T> data), required R error(AsyncError<T> error), required R loading(AsyncLoading<T> loading)}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform some action based on the current state of the AsyncValue.
mapOrNull<R>({R data(AsyncData<T> data)?, R error(AsyncError<T> error)?, R loading(AsyncLoading<T> loading)?}) → R?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform some actions based on the state of the AsyncValue, or return null if the current state wasn't tested.
maybeMap<R>({R data(AsyncData<T> data)?, R error(AsyncError<T> error)?, R loading(AsyncLoading<T> loading)?, required R orElse()}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform some actions based on the state of the AsyncValue, or call orElse if the current state was not tested.
maybeWhen<R>({R data(T data)?, R error(Object error, StackTrace? stackTrace)?, R loading()?, required R orElse()}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Switch-case over the state of the AsyncValue while purposefully not handling some cases.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
override
when<R>({required R data(T data), required R error(Object error, StackTrace? stackTrace), required R loading()}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Performs an action based on the state of the AsyncValue.
whenData<R>(R cb(T value)) → AsyncValue<R>

Available on AsyncValue<T>, provided by the AsyncValueX extension

Shorthand for when to handle only the data case.
whenOrNull<R>({R data(T data)?, R error(Object error, StackTrace? stackTrace)?, R loading()?}) → R?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform actions conditionally based on the state of the AsyncValue.

Operators

operator ==(Object other) → bool
The equality operator.
